Filing an intent-to-use trademark application secures your priority date, but it does not give you a registration. Between filing and owning a registered mark sits a required step that roughly half of all USPTO applicants must complete: the statement of use. Miss it, and the application you spent months prosecuting dies. No grace period. No appeal. Abandoned.
The trademark statement of use is straightforward in concept but unforgiving in execution. This article covers what goes into one, what it costs, and the mistakes that cause otherwise viable applications to fail.
What Is a Statement of Use?
A statement of use (SOU) is a sworn declaration filed with the USPTO confirming that a trademark is being used in commerce, accompanied by a specimen proving that use. It is required for any application filed under Section 1(b) of the Lanham Act, the "intent-to-use" filing basis. Practitioners often refer to it simply as an SOU trademark filing.
The distinction matters. When you file an intent-to-use application, you are telling the USPTO that you have a bona fide intention to use the mark in commerce but have not started using it yet. The application proceeds through examination and publication just like a use-based application. But instead of receiving a registration certificate, the applicant receives a Notice of Allowance (NOA), which is the USPTO's way of saying: "Your mark is approved, now prove you are using it."
The SOU is that proof. It converts a conditional approval into an actual registration.
Intent-to-use filings account for roughly 50 to 60 percent of all USPTO trademark applications. That means the statement of use is one of the most common filings at the USPTO, yet it remains a frequent source of procedural errors. The reason is simple: by the time the NOA arrives, months or years have passed since the original filing. Deadlines get lost. Products change. Teams turn over.
Understanding the SOU process is essential for anyone managing a trademark portfolio that includes 1(b) applications. For a broader overview of the registration process from application to certificate, see the guide to how trademark registration works.
Intent-to-Use vs. Use-Based Filing: Why It Matters
The USPTO recognizes two primary filing bases for domestic applications. Section 1(a) is for applicants already using the mark in commerce at the time of filing. Section 1(b) is for applicants who intend to use the mark but have not yet started.
The strategic advantage of a 1(b) filing is priority. A company planning a product launch can file a 1(b) application months before the product ships and lock in a priority date as of the filing date. If a competitor files a similar mark after that date, the 1(b) applicant has the earlier claim. This is why startups, product teams, and brand owners preparing launches routinely choose 1(b) over 1(a).
The tradeoff is the SOU requirement. A 1(a) applicant submits a specimen with the initial application and, assuming examination goes smoothly, proceeds directly to registration. A 1(b) applicant must wait for the NOA, begin using the mark in commerce, and then file the SOU with its own specimen and fees. That additional step introduces more deadlines, more cost, and more risk of procedural error.
Both paths lead to the same result: a federal trademark registration. The difference is when you prove use. If you are preparing to file and want to understand what each path requires before you begin, the pre-filing checklist covers the documentation you will need.
The SOU Timeline: From Notice of Allowance to Registration
The clock starts when the USPTO issues the Notice of Allowance. This happens after the mark passes examination and survives the 30-day opposition period (the window in which any third party can challenge the application). Once the NOA issues, the applicant has a fixed timeline to complete the statement of use filing or request an extension.
The initial window: 6 months. From the date the NOA issues, the applicant has six months to file the SOU. If the mark is already in use, this is usually straightforward. If it is not, the applicant must either begin use within that window or request an extension.
Extensions: up to 5, at $125 per class each. The USPTO allows up to five extensions of time to file the SOU, each granting an additional six months. Every extension requires its own filing and fee of $125 per class. With the initial six-month period plus five extensions, the maximum total time from NOA to SOU filing is three years.
The hard deadline. If the applicant neither files an SOU nor requests an extension before the current deadline expires, the application is abandoned. The USPTO does not send reminders before abandonment. There is no grace period, and reviving an application abandoned for failure to file on time requires a petition to the Director (under 37 CFR 2.66) with a high bar for success. The priority date, the prosecution history, and the application fees are all lost.
After approval. Once the USPTO examines and approves the SOU, it issues a registration certificate. The registration's priority date relates back to the original 1(b) filing date, preserving the early priority that made the intent-to-use path valuable in the first place.

What Goes Into a Statement of Use
The SOU has four components. All four must be correct for the filing to be accepted.
1. A signed declaration under penalty of perjury. The applicant (or an authorized representative) signs a sworn statement that the mark is in use in commerce on or in connection with all the goods or services listed in the application. This is not a formality. False statements in a sworn declaration can be grounds for cancellation of the registration and, in extreme cases, fraud claims.
2. A specimen showing the mark in use. The specimen is the physical or digital evidence that the mark is being used in commerce. The rules differ depending on whether the application covers goods or services:
- Goods: The specimen must show the mark on the goods themselves, on packaging, on labels, or on tags. A photo of the product with the mark displayed on it is the most common specimen for physical goods. For software, a screenshot showing the mark in the application interface or on a download page qualifies.
- Services: The specimen must show the mark used in the advertising or rendering of the services. Website pages, brochures, and advertisements that display the mark in connection with the described services are typical specimens.
A common point of confusion: advertising materials (brochures, social media posts, banner ads) are generally acceptable specimens for services but not for goods. For goods, the specimen must show the mark associated with the product itself, not just in an advertisement about the product.
3. The date of first use in commerce. The applicant must state the date when the mark was first used in commerce. "Commerce" here means commerce that Congress can regulate, which for practical purposes means interstate or international commerce.
4. Filing fees. The fee depends on the filing method: $100 per class for TEAS Plus filings, $200 per class for TEAS Standard. For a multi-class application, these fees apply to each class separately.

Common SOU Mistakes and How to Avoid Them
The most frequent SOU problems fall into four categories. Each one can result in a refusal, an office action, or worse.
Wrong specimen type. This is the single most common error. Applicants filing for goods submit advertising screenshots instead of product photos, labels, or packaging. The USPTO examining attorney will refuse the specimen and issue an office action. The fix is simple but costs time: understand whether your application covers goods or services, and submit the corresponding specimen type. If your application covers both, you need appropriate specimens for each.
Specimen does not match the mark as filed. The mark shown in the specimen must match the mark in the application. If the application shows a stylized logo and the specimen shows the word mark in plain text (or vice versa), the USPTO may refuse the specimen. Minor variations are sometimes acceptable, but the safest approach is to ensure the specimen displays the mark exactly as it appears in the application.
Missing the deadline. This is the most consequential mistake because it is irreversible. The applicant forgets to file the SOU or an extension request before the current deadline expires. The application is abandoned. Calendar the NOA deadline immediately upon receipt, and calendar reminder dates well in advance. If the mark is not yet in use and you need more time, file the extension request before the deadline. The $125 per class extension fee is a small price compared to losing the application.
Filing for goods or services not yet in use. The SOU declaration states under penalty of perjury that the mark is in use for all listed goods and services. Filing an SOU that claims use for items the applicant is not actually selling or providing is fraud on the USPTO. If the mark is in use for some listed items but not others, a partial statement of use (covered below) is the correct approach.
Partial Statements of Use: A Strategic Option
The USPTO allows applicants to file an SOU for some of the goods or services in the application while requesting an extension of time for the remainder. This is called a partial statement of use, and it is a valuable strategic tool for phased product launches and multi-class applications.
Consider a company that filed a 1(b) application covering Class 9 (software), Class 35 (business consulting), and Class 42 (SaaS platform). If the software is live but the consulting and SaaS offerings are still in development, the applicant can file a partial SOU covering Class 9 and request an extension for Classes 35 and 42.
The key constraint: the three-year maximum runs from the original NOA date, not from the date of the partial SOU. Filing a partial SOU does not reset the clock. If the NOA issued 18 months ago, the applicant has 18 months remaining to file the SOU for the remaining classes, regardless of how many extension requests are still available.
Sometimes the right strategic decision is to drop classes you are unlikely to use within the three-year window. Maintaining speculative classes through repeated extensions costs $125 per class per extension and carries the risk of a fraudulent declaration if you ultimately claim use you cannot support. A clean registration covering the classes you actually use is more defensible than a broad registration built on thin evidence.
For ongoing maintenance obligations after registration, including the Section 8 declaration of continued use, see the trademark renewal guide.
Statement of Use Filing: What Matters Most
The statement of use is the bridge between an intent-to-use application and a federal registration. It is procedurally simple (a declaration, a specimen, a fee) but unforgiving on deadlines and detail. The most common failures are preventable: wrong specimen type, missed deadlines, and overclaiming use.
For any 1(b) application, calendar the NOA deadline the day it arrives. Know whether your goods or services require product-based or advertising-based specimens. And if you are not using the mark for all listed items, file a partial SOU rather than risk a fraudulent declaration.
